List three phenomena which can be explained by the molecular theory of matter.




This is another favorites question among candidates. Majority of the candidates listed at least two phenomena correctly while a few quoted the kinetic theory of matter instead.

The expected answer is:


-           Brownian motion;                             
-           Diffusion;
-           Surface tension;
-           Capillarity (Capillary action);
-           Osmosis

  -           Viscosity
